== my 2 cents== The memory in the computer is lost when the battery is disconnected for an x amount of time on this model car. All the self test the car has run (monitors) need to be performed again by driving the car. IF the check engine light was on, it will come back after it fails the test that it had previously failed for....most likley.
Disconnect the battery for about 10-15 minutes resets the computer, and that means no Check Engine Light after you have fixed/ replaced what was wrong.
Replacing the battery was not likely the cause of your check engine light. Most auto parts stores have a code reader will read the code for you at no charge and reset the light.
It is very easy to reset the check engine light on a 2002 Volkswagen Cabrio. The negative battery cable can be taken off for one minute and replaced to reset the light.
You can reset it with your OBD reader or you can disconnect the negative battery cable for a couple of minutes to reset the check engine light.
did you check the alternator??
Did you reset the Check Engine light? If not, reset by disconnecting the negative battery cable for a couple of minutes. This will erase the computer. Reconnect the battery cable and if everything is OK, the Check Engine light should be off.
on QX4 1997 i got on begining check engine and ABS after i replaced alternator and the battery light goes off and after couple days that come back, i suspected electrical problems
I have a 98 mystique, and when the check engine light comes on, I simply disconnect the positive battery terminal for a couple of minutes. When I replace it, the check engine light is cleared. It resets the computer.
Only the computer can tell what made your check engine light come on. It could be your battery. If your battery is bad, replace it and see if that solves the problem. If it does not, then you will have to connect your car to the computer and find out why the check engine light came on.
i just changed my batterys out on my truck now my check engine light is on?
